Hi,

I think I need to use a Remove() function or something to remove any random ' in a string,

e.g. ''O'Loughlin', 'niffib', '9', '0', 'fghjk', '£10000')'

from the "O'"

Any ideas?

Cheers Richard

This will remove all single quotes from myString...
Code: 
Replace(myString, "'", "")

Hi,

Thanks alot!, veyr prompt! :-)
Can I just ask where i put that?

I have put it in the page where I submit the data, or does it need to be on the data entry pages?

I the following error on the submit with that code...

Code: 
Microsoft VBScript compilation error '800a0414' 

Cannot use parentheses when calling a Sub 

/register/registercv.asp, line 31 

Replace(strSQL, "'", "")

Can you post your code. I wouldn't use this method on your entire SQL string as it will remove ALL single quotes and you probably have some in there that you need - surrounding string variables for example.

for the example you need to escape the ' not remove it, as it is part of a name.

Code: 
strSQL = replace(strSQL,"'","''")

probably the second most asked question after "how do I hide my source code"

Hi, I can imagine that it is a common question...someone should write an FAQ!

This is the page that does the insert..it is the culmination of 3 pages of data entry prior to that.
below this...the error that I am still getting, now that I am using the line from Chris.

Code: 
<%@ LANGUAGE="VBSCRIPT" %>
<!--#include file="md5.asp" -->
<!--#include file="rand.asp" -->
<!--#include file="common.asp" -->


<html>

<%

	Password =  Request.Form("password")
	Sec_ques = Request.Form("sec_ques")
	Sec_Ans =  Request.Form("sec_Ans")
	first_name = Request.Form("first_name")
	last_name = Request.Form("last_name")
	Birth_Year = Request.Form("Birth_Year")
	Address = Request.form("Address")
	Post_Code = Request.Form("Post_Code")
	E_Mail = Request.Form("E_Mail")
	[URL unfurl="true"]www =[/URL]  Request.Form("[URL unfurl="true"]www")[/URL]
	Ethnicity = Request.form("Ethnicity")
	Nationality = Request.form("Nationality")
	Gender = Request.Form("Gender")
	County = Request.Form("County")
	Country = Request.Form("Country")
	PersonTelephoneNoH = Request.form("PersonTelephoneNoH")
	PersonTelephoneNoW = Request.form("PersonTelephoneNoW")
	FeeRate = Request.form("FeeRate")
	CareerDetail= Request.form("CareerDetail")

strSQL = replace(strSQL,"'","''")

conn.Open "D:/Websites/richard/admin/db/users.mdb"

	'Build connection

The error...

do it here instead:
Code: 
last_name = Replace(Request.Form("last_name"), "'", "''")

yes - the ones that contain strings anyway - not much point on the other ones (numeric, boolean, etc).

Before even considering using a 'built-up' SQL query, do a Google for 'SQL injection attack'. When you've read a few of the horror stories that result from it, look up 'stored procedures' or 'parameter queries' and find out how to do it properly
